General description y relating to a taxpayer and the method of calculating tax have been omitted', and only those parts of the forms adapted to receive records in the machine are illustrated herein. In the collection of income taxes, the amount of tax is calculated and entered near the upper righthand corner (Fig. 8) according to the months in which the installments of the tax are to be paid, together With the total amount of the tax. The form is provided with six detachable vouchers, which are consecutively numbered in the order in which the installments are to paid. The tax collector files the return in his oiiice, and, when an installment is due, a voucher is detached therefrom and sent to the taxpayer. In making .installment payments, the vtaxpayer brings the voucher (Fig. 9) to the tax collectors cnice and tenders the amount of the tax. The tax collector removes the form (Fig. 8) from his files and inserts the form in the proper position on the slip table provided therefor in the machine. The voucher is inserted in a voucher receptacle, where the amount of tax paid is entered during the machine operation, and the voucher` is automatically certified in the machine.

In order that the records are complete, both on the form (Fig. 8) and on the voucher (Fig. 9), the machine is provided with certain safeguards so that the machine cannot be operated until the form and the voucher are in the machine. When the form is inserted in the machine (Fig. 8) a lock for the machine release mechanism is unlocked by the form itself; that is to say, when the form is inserted in the machine, the machine release shaft lock is actuated. When the voucher is dropped into its receptacle, a second lock for the machine release shaft is also actuated. Thus two locks are provided for the release shaft, one operated by a form 18| (Fig. 8) and the other operated by a voucher 2 I 0 (Fig. 9). The voucher may be overlooked by the operator and left in the machine, which would result in the taxpayers not getting a proper receipt. In order to warn the operator that the voucher was not removed from the machine, a third lock is provided, which lock becomes effective at the end of the machine operation and which remains effective until the voucher is removed from the voucher receptacle. Removal of the voucher from the receptacle renders said second lock effective, and, before the machine can be released for a subsequent operation, another voucher must be placed in the voucher receptacle.

The data set up in the machine which is to be printed on the form (Fig. 8) and on the voucher (Fig. 9) is set up by the usual lever, shown in the above-mentioned Breitling patent. In addition to the entries made on the insertable forms, an entry is also made on an audit tape. Therefore the machine is provided with three lines of type wheels which are adjusted by the amount levers of said machine.

Detailed description The machine to which the present invention is shown applied is provided with a series of setting levers 30 (Fig. 7) Divotally mounted on a cam shaft 3l. Each lever 30 is provided with a series of teeth 32, meshing with a pinion 33, secured to a shaft 34, which shaft extends into the printer section of the machine and by means of which type carriers are positioned commensurate with the setting of the levers 30.

The lever 30, shown in Fig. 7, is shown for adjusting the type carriers through the shaft 34. Other levers, similar to the lever 30, are provided, each of which is provided with teeth 32, meshing with pinions 33, which pinions are connected to nested sleeves for setting up type carriers in the printer.

The lever 30 is provided with alining notches 35, engageable by a stud 36 on the lever 39, pivoted on a shaft 31, and held in the position shown by a spring 38. As the lever 30 is adjusted for setting up an amount, the stud 36 ratchets in and out of the notches 35. As fully described in the above-mentioned Breitling patent, means is also provided for locking the stud in a notch 35 during the machine operation to prevent manipulation of the lever 30 during a machine operation.

The upper end of the lever 30 projects through 4- a slot in the cabinet of the machine, where the lever can be manipulated.

Each of the amount levers carries a stud 40, which cooperates with a corresponding arm 4|, loose on the shaft 3l, which arm 4I is connected by a link 42 to an arm of a segmental gear, or totalizer driving member, 43, loose on a rod 44, supported by similar plates 45, and the arms 4I are pivotally supported on a shaft 45, journaled in the framework of the machine. The plates 45 are held in rigid relation to each other by the rod 44, the entire assembly forming a rockable frame adapted to rock the teeth of the segments 43 into engagement with similar teeth of the corresponding totalizer gear 41, rotatably mounted on a shaft 48 supported by the framework of the machine. The gear 41 meshes' with a pinion integral with a corresponding totalizer wheel 49, free on a shaft 50, supported by the framework of the machine.

A spring 5 I, tensioned between each of the segments 43 and the arms 4i, urges said segments and arms counter-clockwise, as viewed in Fig. 7, to maintain the arms 4i in contact with the studs 40. It is therefore evident from the foregoing ded scription that positioning of the lever also positions the corresponding segments 43 to similar' positions.

Each of the plates carries rollers 52 and 53 adapted to cooperate with their respective companion plate cams 54 and 55 fast on the main shaft 3|. As described hereinafter, rotation of the main shaft 3| one clockwise revolution completes operation of the machine. Initial movement of the shaft 3! causes the cams 54 and 55.', in cooperation with the rollers 52 and 53, to rock the framework, composed of the plates 45, counter-clockwise to engage the teeth of the segments 43 with their corresponding totalizer gears 41. After the segments 43 have been engaged with the gears 41, continued movement of the main shaft 3l causes a cam 56 for each denominationalorder, secured on the main shaft 3i, to engage corresponding rollers 51, mounted on the links 42,! and return the segments 43 from set positionV clockwise to normal position. This rotates thei totalizer Wheels 49 proportionately to the amount set up on the amount levers 30 to enter said amount in said totalizer wheels.

A dwelling portion in the peripheries of the cams 56 causes the segments 43 to remain in zero position until further rotation oi the shaft 3l causes the cams 54 and 52j to rock the segment frame clockwise to disengage the segments 43 from the totalizer gears whereupon declining surfaces on the cams permit the springs 5l to return the segments 33 and their associated links 42 and arms 4l counter-clockwise to their set positions, which positions are determined by the arms 4I contacting the studs (ill.

A tens transfer mechanism, as shown and described in the above-mentioned Breitling patent, is provided for transferring from the lower orders to the higher orders, when the lower orders pass through zero.

Operating mechanism,

The machine may be operated by means of a manually-operable hand crank (not shown, but well known in the art) or by an electric motor.

When an electric motor is provided, a gear (not.v shown) is driven by the armature thereof, which.

ratchet wheel 6|, and the assembly, including the gear 60 and the ratchet wheel 6|, is rotatably mounted on a stud 62, carried in the left side frame of the machine. Also mounted on the stud 62 is a disk 63, carrying a clutch pawl 64 pivotally mounted on a stud 65 thereon. A spring 66, connected to one end of the clutch pawl 64 and to a stud carried by the disk 63, normally tends to move the clutch pawl 64 into engagement with the ratchet wheel 6|. When the machine is at rest, a stop arm 61, described later, lies in the path of an upstanding arm 68 of the clutch pawl 64, and the arm 68 is engaged by a stud 69 on the disk 63 to thereby provide a positive stop for the disk 63.

When the machine is released for operation in a manner described hereinafter, the stop arm 61 is raised out of engagement with the arm 68, thus permitting the spring 66 to move the clutch pawl 64 into engagement with the ratchet wheel 6|, which at this time is being rotated by the motor. When the clutch pawl 64 drops behind a tooth of the ratchet wheel 6|, the ratchet wheel carries the pawl, together with the disk 63, counterclockwise. As the upstanding arm 68 again'approaches home position, the arm 61 is again lowered, in the manner described hereinafter, into the path of the upstanding arm 68, thus forcing the upstanding yarm 68 against the stud 69 and thereby arresting the disk 63 after the main shaft 3| has completed one complete rotation. Also secured to the disk 63 is a gear 1| meshing with a gear 12 secured to the main shaft 3|. Therefore, when the disk 63 is arrested, the

gears 1|' and 12, and the main shaft 3|, are arf rested, after the main shaft makes one complete rotation. The ratio between the gears 1| and 12 is l to l, In other words, one complete rotation of the gear 1| causes one complete rotation of the gear 12 and of the main shaft 3|.

Machine release mechanism After the levers have been properly positioned, the machine may be released for operation by the depression of a motor bar 15 (Fig. 5),

depression of which releases mechanism to withdraw the arm 61 from engagement with the upstanding arm 68 of the clutch pawl 64, and also operates mechanism to close a switch through the motor to start the motor in operation.

The motor bar 15 (Fig. 5) is removably mounted on two studs 16 carried by a slide 11. The slide 11 is slotted to slide on three studs 18, 19, and 80, carried by the right side frame 14 of the machine. A spring 8|, having one end connected to a stud on the slide 11 and the other end to a stud in the side frame 14, normally maintains the slide 11 in its upward position, where its movement is limited by studs 18 and 19. The slide 11 is provided with a stud 82, projecting into a cam slot 83 of a lever 84, pivotally mounted on the main shaft 3|. The lower end of the lever 84 is bifurcated to engage over a stud 85 mounted in an arm 86 secured to a machine release shaft 81. A multiarmed lever 88 is pivotally mounted on a stud 89, carried by the side frame 14, and one arm thereof is provided with an enlarged head 90 normally held against a flange 9|, on the arm 86, by a spring 98.

Depression of the motor bar 15 moves the slide 11 downwardly, thus moving the stud 82 in the cam slot 83 to cam the lever 84 clockwise. A clearance slot is provided in the lever 84, engaging the stud 80 to permit such a movement.

Clockwise movement of the lever 84, through 6 the stud 85, rocks the arm 86 counter-clockwise, thus removing the flange 9| from beneath the surface 90, to free the multi-armed lever 88 to release the machine in a manner to be described presently.

Simultaneously with the lowering of the slide 11, a flange 92 on the slide 11 is moved out of the path of an enlarged head 93 on an upwardlyextending arm of the multi-armed lever 88. Thus, when the flanges 9| and 92 are withdrawn from the respective enlarged portions and 93, the spring 98 can rock the multi-armed lever 88" counter-clockwise (Fig. 5).

A rearwardly-extending arm of the multiarmed lever 88 is bifurcated to engage a stud 94 on an arm 95, secured to a shaft 96, carried by the framework of the machine. Also secured to the shaft 96 is the beforementioned arm 61. Therefore, when the multi-armed lever 88 isrocked counter-clockwise by the spring 98, the arms 95 and 61 are rocked clockwise to withdraw the end of the arm 61 from engagement with the upstanding arm 68 of the clutch pawl 64, thus releasing the clutch pawl 64 to the action of its spring 66, to cause the main shaft of the machine to start its operation.

Also secured to the shaft 96 is a switch operating arm 91, which is adapted to close a switch through the electric motor, in the manner well known in the art and not shown herein.

The multi-armed lever 88 and the arm 61 are restored to their normal positions near the end of machine operation by a stud |08 (Fig. 5) mounted on the side of a gear |0|, secured to the main shaft 3|. When the multi-lever 89 is released to the action of the spring 98, upon depression of the motor bar 15, and the multiarmed lever 88 is rocked counter-clockwise, a cam surface |02 is moved into the path of the stud |00. Then, near the end of the operation of the main shaft 3|, when the -stud |00 approaches the terminus of its movement, the stud |00 engages the cam surface |02 on the multiarmed lever 88 and rocks the arm clockwise back to its normal position. At this time, the arm 86 is moved to position its flange 9| under the enlarged surface 90 by a spring |03, secured to a rod |04, to which is also secured a plurality of arms |05 secured to the shaft 81. Restoration of the arm 86 also restores the lever 84 to its normal position, thus permitting the stud 82 to rise in the cam slot 83 and permit the slide 11 to be restored to its home position by the spring 8|. Simultaneously with the restoration of the slide 11 to its normal position, it positions the flange 92 into the path of the enlarged end 93 of the multi-armed lever B8.

A non-repeat pawl |06 is pivotally mounted on a, stud |01, carried by the multi-armed lever 88, to which is also attached a spring |09. The spring |09 normally maintains a stud l0 against one side of an arm of the multi-armed lever 88. When the slide 11 is lowered by depression of the motor bar 15, the flange 92 engages the upper side of the pawl |06 and rocks it counterclockwise. Upon release of the motor bar 15 before the end of the machine operation, the flange 92 is again raised, thus freeing the pawl |06 to the action of the spring |09, whereupon the parts' assume the position shown in Fig. 5. If, however, the operation should hold the motor bar depressed until the end of machine operation, then, when the multi-armed lever 88 is restored to its home position by the stud |60, the pawl |06 is rocked from beneath the flange 02,- vvhereupon the spring |09 snaps the pawl |06 into position to engage the right side of the flange The flange 92 therefore prevents the multi-armed lever B from .being restored to its home position, and therefore the machine cannot be released for another operation until the operator removes his finger from the motor bar 15. When he releases his finger yfrom the motor bar to permit the spring 8| to restore the motor bar 15 to its home position, the ange 92 passes beyond the end of the pawl |06, thus permitting the spring |09 to restore the multiarmed lever B0 to its home position, ready for the next operation of the machine.

Type-setting mechanism The shaft 34 (Fig. 1), together with the nest of sleeves H5, surrounding the shaft 34, is adjusted in accordance with the position of the levers 30 (Fig. 7), as hereinbefore mentioned. rlhe shaft 34 and the sleeves H5 project into the printer section of the machine (Fig. l). Secured to the shaft and to each sleeve H5 in the printer section cf the machine is a gear H6, each meshingwith three type wheels H1, H8, and H5. The type wheels Hl' are provided to set up data to be printed on the insel-table vouchers shown in Fig. 9. The type wheels H8 are provided to set up data to be printed on the audit tape hereinafter described, and the type wheels H9 are provided to set up data to be printed on the printed form shown in Fig. 8'. The type wheels HB and H9 are rotatably mounted on shafts and |2|, respectively, carried by the left side frame |22, and on an auxiliary frame, not shown. The type wheels H1 are carried on sleeves provided with gears (not shown) which mesh with the gears H6.

Type wheel aliner When an aliner is rocked in a manner hereinafter described, it engage-s all of the gears H0 and simultaneously alines the three lines of type wheels H1, H8, and H9.

The aliner |30 is pivotally mounted on a shaft |35, carried by the side frame |22 and the auxiliary frame (not shown). One arm of the aliner 30 extends downwardly and is provided with a stud |32 coasting with a cam |33 on the cam shaft 55. Also secured to the shaft 4S (Fig. 5) is a gear |35 meshing with an intermediate gear |31 rotatably mounted on a shaft |33. The intermediate gear |31 meshes with a gear |39 rotatably mounted on the shaft |40. The gear |33 meshes with. the beforementioned gear |0|, secured to the main shaft 3| of the machine. Therefore, when the main shaft 3| 'receives its clockwise rotation, the shaft 40, through the gears |59, |31, and |36, is rotated counter-clockwise (Fig. 5) and clockwise (Fig. 1). At the beglnning of machine operation, the cam |33, co acting with the stud |32, rocks the aliner |30 to engage its aliner `bar with the teeth of the gears i i5 to aline the type wheels in the manner before described.

Audit tape All the data entered into the machine is ren corded on an audit tape (Fig. 1). The audit tape is fed from a supply 1'011 |45 rotatably mounted on a stud |41 carried by a removable frame. The audit tape is fed around suitable guide rollers |48 and a stud |49 over an ink supply roller |50 to a receiving roll |5I. The supply roll stud |41, the guide rollers |48, the stud |40, the ink supply roller |50, and the receiving roll |5| are all carried on a frame which is removable from the machine for easy replacement of the audit tape supply roll.

' The end of the audit tape is held on the receiving roll |5| by a key |52 in the usual manner. Secured to the side of the receiving roll |5| is a feed ratchet whe-el |53, with which an actuating arm |54 engages to line-space the audit tape during each operation of the machine. The arm |54 is secured to a shaft |55 carried in the framework of the machine. Also secured to the shaft |55 is a gear |50 meshing with a gear |51 rotatably mounted on a stud |58. The gear |51 meshes with a gear |59 on the main shaft 3|.

When the main shaft 3| is given its complete rotation during the machine operation, the shaft |55 is also rotated through the gears |59, |51, and |56 to rotate the arm |54 one complete rotation. As the shaft |55 nears the end of its rotation, the arm |54 engages between teeth of the ratchet wheel |53 and rotates the receiving roll a distance suliicient to line-space the printing on the audit tape.

A non-retrograde alining pawl |00 is pvoted on a stud |6| carried by the removable audit tape frame. A spring |02 urges the pawl |60 into engagement with the teeth of the ratchet wheel |53. The pawl is provided with two bevel edges normally engaging on each side of a tooth of the ratchet wheel, thus providing a means for preventing non-retrograde movement and also accidental rotation in a feeding direction.

Audit tape printing hummer The data is recorded on the audit tape by a printing hammer |10, slidably mounted on a stud |1| and on a shaft |12. A spring |13 normally maintains the hammer in its retracted position.

The hammer is impelled against the action of the spring |13 by a cam |14 secured to the shaft |12. Also secured to the shaft i12 is a gear |15, meshing with the beforementioned gear |56. The hammer |10 is provided with a roller |18 lying in the path of the cam |14. When the cam |14 is rocked during each operation of the machine, the cam, coacting with the roller |16, impels the hammer |10 to carry the audit tape against the type wheels H8 to record thereon the data set up on said type wheels. An ink ribbon |11 is fed through the machine past each of the sets of type wheels H1, H8, and H9, to provide means for recording the data on the audit tape. The ribbon mechanism is described hereinafter.

Slip printing mechanism A table is provided, which is supported on the framework of the machine to receive the printed form |8| (Fig. 8) for recording the data thereon from the set of type wheels H9. The table |80 is provided with suitable adjustable stops, which are adjusted to properly aline the spaces on the form in which the data is to be entered. As will be observed by referring to Fig. 8, there are six areas on the form |8|, in which data is to be entered, and each area is allotted to a definite pay period. The stops are positioned for the particular pay period. For example, when the March taxes are due, the area indicated by the legend receipt will be positioned in line with the printing wheels ||9 and an electro plate |19. 'When the May paiy period becomes due, the adjustable stops are set so that, when the form |8| is inserted in the machine, the area carrying the legend receipt ass-ci #2" will be positioned to receive the printed data. The adjustable stops are so arranged that any one of the six areas can be located with reference to the printing wheels |28 and the electro plate The data is entered on the form |8| by a hammer |85, located beneath the table |80. A suitable opening is provided in the table |80 to permit the hammer to pass through the table and carry the form |8| thereon and the ribbon |11 against the type wheels |9 and the electro plate |19. The hammer |85 is pivotally mounted on a stud |88, and the hammer carries la roller |81 at its free end. The cam |88 is secured to a shaft |18 in position to be engaged bythe roller |81. A gear 35, secured to the shaft |18, meshes with a gear i8@ on the shaft 46. When the shaft 46 is rotated in a clockwise direction, the cam |88 is rotated by the gears |38 and |35, and the cam |88, coacting with the rolier |81, lifts the hammer |85 and carries the platen thereon into engagement with the under side of the form |8| and carries the form and the ribbon |11 against the type members. After the impression has been made and upon continued rotation of the cam |88, the hammer 85 drops to normal position, as controlled by the cam |88, under the action of gravity.

Slip holding means A means is provided to hold the form |8| against accidental shifting during the printing operation thereon. The means for holding the form |9| against accidental shifting includes a pair of arms |90 rotatably mounted on the shaft 81 and side-spaced so as to grip the insertable slip adjacent the ends of the printing platen or hammer |85. To grip the form, the arms |90 are provided with a pair of holding surfaces |9|, which are moved into their elevated positions by a spring |92, one end of which is connected to a stud on one arm |98 and the other end is connected to a stud on the machine frame. A suitable opening is provided in the table |80 to permit the spring to elevate the arms therethrough, after which the form is elevated and impinged against a guard plate |93, located slightly above the table |80.

When the machine is at rest, the gripping means |9| are held in the lower position by a cam |95, normally lying in the path of a stud |96 supported between the two arms |90. When the shaft 18 starts to rotate at the beginning of the machine operation, the cam |95 is rotated out of contact with the stud |90 to permit the spring |92 to elevate the arms |98 and cause the gripping ends i9| thereof to pass through the opening in the table 80 and grip the form between said arms and the guard plate |93. Near the end of machine operation, when the cam |95 returns to its home position, the cam, engaging the stud |96, lowers the gripping arms |90 and restores them into the position shown in Fig. 1.

Machine release contfroZ by the nsertable ,form

In order that the machine cannot be operated without the form |8| being in proper position, a means is provided to normally lock the release shaft 81 against releasing movement until the form is in proper position. This means includes a locking arm 200 pivotally mounted on a shaft 20| carried by the framework of the machine. The arm 200 is urged counter-clockwise by a spring 202 and is limited in such movement by a stud 203, to which one end of the spring 202 is also attached.

A forward extension 200 of the locking arm 200 normally lies in the path of a stud 205 on an arm 208 secured to the release shaft 81. Therefore, as long as the arm 200 is in the position shown in Fig. 1, the release shaft cannot move, and therefore the machine can not be released for opu eration. The insertion of a form i8| in the table rocks the locking arm 200 clockwise a distance sufficient to withdraw the extension 204 from the stud 205. For this purpose, the upper end of the locking arm 200 is shaped in the form of an angle, which normally projects through an opening in the table |80 and to a recess formed on the guard plate |93. When the form |8| is positioned on the table and moved into proper position, the form, engaging the angle surface on the locking arm 200, rocks the locking arm 200 clockwise until the form. is free to pass over the apex of the angle on the free end of the locking arm 200. This movement of the locking arm 200, which is imparted by the insertion of the form, is sufficient to withdraw the extension 200 from the path of the stud 205 on the release shaft, and therefore the machine can be released in the manner hereinbefore described. The spring is of light construction to permit the form |8|, which is printed on paper stock stiff enough for the purpose, to obtain the results described.

Voucher printing mechanism The voucher 2|0 (Fig. 9) is certified by the machine by being inserted into a receptacle provided therefor before the machine is released for operation. A receptacle 2|| is supported in the framework of the machine and is provided with a slot 2|2, into which the voucher 2|@ is positioned. Normally, the machine release shaft 81 is locked against releasing movement when no voucher 2|9 is in the receptacle 2| l. Positioning of the voucher 2l0 into the receptacle release mechanism, presently described, to permit the release of the machine. Also, if the operator should forget to remove the voucher from the receptacle 2| l after the machine has completed its operation, the machine release shaft 81 will be automatically locked against releasing movement until the voucher is removed therefrom and a new voucher inserted therein. f

Voucher-controlled machine locking 'means In addition to the previously described locking means,..the machine release shaft 81 is normally locked against releasing movement by a locking member ZES (Figs. l, 2, 3, and 4). Connected to one of the beforementioned arms |85 is a link 2|4, also connected to a yoke 2|5, pivoted on a shaft 2 I6. The yoke 2 I5 has formed thereon an arm 2|'|, on which a stud 2|8 is mounted. The stud 2 I8 is engaged by a bifurcated end of an arm 2|9 pivoted on a shaft 220. The arm 2&9 is pro vided with a forwardly extending finger 22 nor mally resting on the upper end of a finger 222 of the beforementioned locking member 2id. The looking member 2li-' is pivoted on a stud 223 and is provided with a yoke normally bearing against the shaft 224, where it is held by a spring 228. An arm 225 on the member 2 i3 enu ters openings in the slot 2|2 so as to lie in the path of the voucher when the voucher is inserted therein.

As long as the upwardly-extending finger 22 lies in the path of the finger 22 l, the machine release shaft 81 is locked against rotation. The

insertion of the voucher 2|0 into the slot 252 en! gages the arm 225 and rocks the locking member 11 2|3 clockwise to withdraw the finger 222 from the path of the linger 22|. Thereafter, upon depression of the motor bar 15, when the shaft 81 is released, the arm 2| 9 is free to rotate clockwise and permit the release of the machine for operation.

As long as the voucher 2| remains in the slot 2i2, the linger 222 remains out of the path of the finger 22|, and therefore the machine could be released for operation without the removal of the voucher 2| from the slot 2|2. It is desired to prevent such repeat operation before the voucher 2 I 0 has been `removed lfrom the machine. in order to accomplish this, a second means is provided for preventing the rocking movement of the arm 2|3 when the voucher 2|0 is left in the slot 2|2 after the completion of a machine operation. Pivotally mounted on the rear end of the latch member 2|3, on a stud 230, is an interpenent 23|, which normally lies against a rod 232. When the machine is released for operation, a downwardly-extending linger 233 of the arm 2|9 moves against one side of the interponent 23|, as shown in Fig. 3. The upper end of the interponent is provided with 4a notch 234, which is a a clearance notch to engage a camming member 235, secured to a rotating shaft 236. The shaft 236 receives one complete counter-clockwise rotation (Figs. 2, 3, and 4) during each machine operation by means hereinafter described. Near the end of this complete rotation, the cam member 235 moves into engagement with the under side of the interponent 23| and moves the interponent into engagement with the downwardly-extending finger 233 of the arm 2|9 after the arm 2| 9 has been restored to its normal postion.

lThe relative positions of the parts at the end of a machine operation, with the voucher 2|0 remaining in the slot 2|2, are shown in Fig. 4. This ligure shows that the finger 233 is engaged by the interponent 23|, and that the interponent 23| is held against the cam member 235. Therefore, if an attempt is made to release the machine for operation by the depression of the motor bar 15, the interponent 23| and the cam member 235 prevent the arm 2|9 from rocking clockwise and therefore prevent rocking movement of the release shaft 81. Thus, so long as the voucher 2|0 remains in the slot 2|2, the machine cannot be released for operation. When the voucher 2|0 is withdrawn from the slot 2 2, the locking member 2|3 drops in a counter-clockwise direction to withdraw the interponent 23| from between the the nger 233 and the cam member 235. At this timeI the parts assume the position shown in Fig. 2, and, upon the insertion of another voucher into the machine, the locking member 2|3 is again rocked clockwise to permit the machine to be released for operation.

As mentioned before, the notch 234 is merely a clearance notch to permit the interponent to rise when a voucher is positioned into the slot 2|2. This notch has no other function.

The shaft 236 is rotated by a gear 231, sleeved to the gear |51. The gear 231 meshes with a pinion 238 secured to the shaft 235. Thus, when the machine is operated and the main shaft 3| receives its rotation, the shaft 236 is rotated through the train of gears including the pinion 238 and the gears 231, |51, and |59.

Voucher printing mechanism The data printed on the lower line 245 (Fig. 9) of the voucher 2| Q is recorded thereon by eprint-v Ribbon mechanism The ribbon |11 is illustrated by dot-and-dash lines and is of the endless type, supported on rods carried by a removable frame in the machine in the usual manner. The ribbon is fed over an ink roller 250, provided with a ratchet wheel 25|. A feed pawl 252 is spring-urged to engage a ratchet wheel 25|, and the right end (Fig. 1) of the pawl 252 is pivoted en a lever 253. The lever 253 is pivoted on a stud 254, and its upper end is provided with a roller engaged by the beforementoned cam |14. During each operation of the machine, the cam |14 rocks the lever 253 clockwise to space the ribbon one step. A spring 255 restores the lever 253 to its home position as the high point of the cam |14 passes from engagement with the roller on the lever 253.

Summary of machine release controls From the above it is clear that the machine release shaft 81 is controlled from four sources. First, the releasing movement of the shaft 81 is under control of the motor bar 15. Second, the form |8| must be in position on the table |80, and the arm 20B must be disengaged from the stud 205. Third, the locking member 2|3 `must be withdrawn from the linger 22| of the arm 29. In addition, as long as the voucher -remains in the voucher slot 2|2 at the end of the machine operation, the interponent 23| prevents release of the release shaft 81 until after the voucher 2|0 is withdrawn from the slot 2|2 to Withdraw the interponent 23| from the path of the finger 233.

While the form of mechanism shown and described herein is admirably adapted to fulll the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form or embodiment disclosed herein, for it is susceptible of embodiment in various other forms.
